Just checking in to see how you're doing... I know it's only been ten days, but you and your family are still in my thoughts. Several people have suggested professional help during this stressful time. I hope you take their advice. It can make a real difference.
Even just taking a few moments during the day to notice things can make a difference.What I mean is, even though it doesn't seem possible with your father gone, the world continues on. I remember feeling really angry about that when my Dad died. How can everything continue on when he's gone? But now, (six years later) I can see a plane flying over and think of him and his love of flying, and there is a peacefulness that comes. It does get better.
In the mean time, for your own well-being, try to take a moment to look out the window, take a deep breath, notice that the spring rain is so much softer than in the fall. Notice that the trees are getting leaves again. Walk in the park barefoot and notice how nice the grass feels. Don't mean to get maudlin, but you get the idea. Maybe you just notice that the chicken wings taste extra spicy and the beer is nice and cold.

Last week I was MD'ing at the park, and a butterfly landed on me. Now... I'm not exactly a hearts and flowers kind of gal, and I promise I don't have a collection of butterfly magnets on my refrigerator, but it was still kinda' neat. My point is, even in the worst of times, there is still beauty in the world, if we just take time to notice. Sorry this post kinda' dragged out.
You're in my thoughts.
Stay well -
